SPRING-BOTTOM FOR BEDS.

Specification of Letters Patent.

Patented Oct. 30, 1917.

Application filed. June 15, 1916. Serial No. 103,902.

To all whom it may concern:

Be it known that I, STEPHEN STRANSKY, a citizen of the United States,residing at Philadelphia, in the county of Philadelphia and State ofPennsylvania, have invented certain new and useful Improvements inSpring-Bottoms for Beds, of which the following is a specification.

My invention consistsv of an improved spring bottom for beds. One of theobjects of my invention is to provide a structure of the above describedtype which will be durable, efficient in its resiliency and can beadjusted to vary the flexibility and tension of the supporting membersthereof.

A further object is to so construct my improvedspring bottom that it maybe quickly and easily positioned upon or removed from a bed, and theseveral parts constituting my invention may be quickly and easilydetached and assembled.

These objects, and other advantageous ends which will bedescribedhereinafter, I attain in the following manner, reference beinghad to the accompanying drawings in which Figure 1 is a fragmentary planView of my invention.

Fig. 2 is a sectional elevation taken on the line a-c of Fig. 1.

Fig. 3 is a transverse sectional elevation taken on the line b b of Fig.2.

Fig. 4 is an enlarged sectional elevation of one end of a supporting andguiding tube showing certain ad]ustable members in connection therewith.

Fig. 5 is a fragmentary detached eleva' tion'showing certain of theelements of my invention. I

Figs. 6 and '7 are perspective views of certain of the elements of myinvention.

Fig. 8 is a fragmentary end view of one of the two tubular supportswhich I employ and which shows a slot 25 formed therein.

Referring to the drawings, 1 is a frame having transversely ext-endingchannel, bars 2, and longitudinally extending bars 3. I

I have illustrated only one of the longi-, tudinally extending bars 3,but it will be understood that the frame 1 consists of two of thetransverse channel bars 2, and two of the longitudinally extending bars3 to complete the rectangular frame.

Each of the channel bars 2 is provided with two holes 4, one adjacenteach end, and

through tllGSB'llOlGS depend sleeves 5 having cup-shaped upper ends 6 oflarger diameter than the holes 4, so that the sleeves will be suspendedby the cup-shaped heads 6. Each of the, sleeves 5 has a tube 7 slidabletherethrough, and each tube has a cotter pin 8 designed to engage thelower end of its sleeve 5.

The upper end of each tube 7 is beaded at 9, and a cup 10 is fittedthereon but is prevented from sliding 05 the upper end of its tube dueto the beaded end 9 forming an abutment.

Spiral springs 11 surround each of the tubes 7, and have their oppositeends respectively engaging the cups 6 and 10, so that any downwardmovement of the tubes 7 will be cushioned by the springs 11, the cotterpins 8 serving to prevent the springs 11 from moving the sleeves beyonda pre-determined upper position, said position being shown in Fig. 2. r

The frame 1 may be secured to the bed proper in any desired manner.Above the frame 1 and the previously described elements, are two tubularsupports 12, there being only one illustrated in the accompanyingdrawings, however, it will be understood that these tubular supportsextend parallel to each other, and each is shaped in a manner similar tothat shown in Figs. 1 and 2.

Each tubular support 12 has a longitudinally extending slot 13 at oneend to provide sliding room for projections 14 on stretching members 15.These stretching members 15 are placed one within each end of thetubularsupports 12 having the slots 13 therein.

Each of the stretching members 15 has a threaded opening 16 into whichfits the threaded stems 17 of adjusting screws 18.

Casings 19 are secured to each end of the tubular supports 12, and haveends 20 which abut the ends of the tubular supports 12,

thus acting as retaining means to keep the stretching members 15 withinthe tubular supports 12. Each adjusting screw 18 has a head 21 waichextends through a hole in its adjacent casing 19, and handles aresecured on the heads 21 and have annular flange 23 which abut the outersurfaces of the ends 20 of the casings 19.

Each of the threaded stems 17, is provided with a threaded collar 2%which is mounted with n the casing 19 and acts to preventaccidentallongitudinal movement of the threaded stems 17. The opposite end of eachof the tubular supports 12 is slotted longitudinally at and this slotextends to said opposite'ends of the tubular supports so as to permitthe insertion of memhers which are of the same construction as thestretching members 15.

The upper extensions of each of the members 15 and 26 are hapecin crosssection, the head of the-T being indicated in each instance at 2'7.

Transrerselj elitending angle lEJTS 2S and 29 each hare slotted openingsthrough which the T-shaped projections of the members l5 and 2) may beinserted.

A flexible fabric 31, which may be n'ride up of a series of flexiblyconnected links having side links hinged at 3l,'is connected by a seriesof tension springs 35 to the upwardly projecting legs of the angle bars28.

The ends of the tubular supports which have the slots 25 therein, areprovided with casings which of similar constructitui to the casingslharing ends 37 which form abutments for said latter ends of thetuhular's'upp'orts 12.

Each of the casings l9 and 36 has a downwardly projecting pin 38. Eachof these pins 38 is designed to engagea respecti e tube '7 as clearlyshown in the lower portions of the casings l9 and on engaging the upperleaded ends 9 of said tubes, so that all of the weight supported by thetubular supports 12 is in turn suppor ed by the spring-pressed tubes 7.

As a means for securing the bars 3 "o t ie channel bars '2, I provideplates 39, each having an end to engaging the lo Yer surface of thechannel bars and an up-turned flange a l which engages the outer facesof the bars The lower edges of the bars rest on the upper surfaces ofthe plates (sec and clamping means including screw bolts and wing nuts ttend to bind the plate and the bars and 3 together.

Each of the plates is preferably provided with a slot sit to'perniitofany lateral adjustment necessary, this slot being of such width as topermit the free movement of the threaded end of the screw bolt as"therethrough, but of smaller width than the diameter of the sleeveportion %5 of the wing nut as.

It will thus be understood that the springs 11 f, in resilient supportto accommodate any direct- Yertical increment required by the tubularsupports 12' and their co-acting elements, and the springs yield topermit the desired flexing of the links 32 and side members More or lesstension may be placed upon the links and members 33 by turning movementof the handles since the morem'ent of the handles causes a relativemovement of the threaded stems 1'7 and thereby effects movement of thestretching members 15.

flhe' uembers 26 will, in their opera-tire positiom engage the inner endof the slot 25, and thereby prevent further movement toward the middleof the tubular supports 1 Each of the cups 6 on the tubes 7 is providedwith ears i7 having holes therein thrmigh which screw e8 may be securedto the channel liars 2. so that the tubes are ri idlyl old to saidchannel liars.

The cas ngs l9 and 36 are each open their upper ends to permittheprojections of the 1T1BI11l39lS l5 and 26 to extend therethrougln sothat a positive and free sliding movement maybe securedb} the stretchingmembers which act to more the angle bars 28 in t e direction of theslots 13. 7

The casings 15) and 36 are held secure-l to the tubular supports 12 bymeans ofset screws that said supports formsta- 'ionary gnideways andpormitthe stretching n1 mbers to slide freely and easily.

will be further understood that if it is desired to remote thetubularsupports and the parts connected thereto from thetubes 7, it ismerely necessary to raise the pins 38 out of the tubes. Furthermore, theangle bars 28 may be removed bodily with the flexible fabric 31 andsprings 35 by turning the handles to permit the rearward movement of thestretching members 15'to such position that the T-shaped heads of saidstretching members are opposite the corresponding openings within theliars 28 when the entire superstructure may he raised therefrom.

ll hile l have described my intention as taking a particular form, itwill be understood that the various parts of my invent-ion may'bechanged without departing from the spirit thereof. and hence I do notlimit myself to the precise construction, set forth, but consider that'lam at liberty to make such changes'and alterations as fairly come can inthe scope of the appended claims.

Having thus described my invention, what I'claimas new and desire tosecure by Letters Patent is:
